The feasibility of employing an array of three ground-based beacons operating as distance measuring equipment DME transponders to accurately guide a projectile to a target is explored. For simplification of the problem, the projectile is assumed to be a point mass, with only drag, gravity and control forces acting on it. A projected planar guidance law is adopted for the projectile and it is assumed that the guidance law can be implemented exactly. Estimates of targeting errors are obtained by computer simulation, as functions of beacon-to-beacon spacing, guidance cut-off altitude, terminal velocity, and beacon location errors. Results of a statistical analysis on the computer simulations indicate that the major parameters affecting the desired accuracy at the target are beacon-to-beacon spacing and beacon-target geometry.
